Comment 65 for bug 1875199

@Kai-Heng,

Thank you very much for your efforts here. I just wanted to provide a quick update...

Short version - I have been able to repeat the positive result using the updated kernel you provide on a fresh install of Ubuntu 20.04.1 (the recent point release).

More detail -

Since Ubuntu 20.04.1 was just released, I decided to completely erase the system once again and install Ubuntu 20.04.1 from the latest .ISO

I performed the installation and then applied all of the software updates (there were not very many, which I understand is to be expected).

While in this 'fresh' state, the audio output did not work (which again was expected).

I followed the same procedure as I did before (as described in comment #60 --> https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1875199/comments/60) to install the updated kernel you provided in comment #59 --> https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1875199/comments/59

When I did so, as happened before all but one of the packages installed properly. I have provided the full text of the error in the attached file 'installation_log_ver2.txt'

Despite this error, I rebooted the system.

Upon rebooting, the system provides this output from running 'uname -a':

Linux NUC8CCHK 5.4.0-42-generic #46-Ubuntu SMP Fri Jul 10 00:24:02 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

I make mention once again only because I am unsure if I did anything incorrectly, so I wanted to make you aware.

That said, I did experience the same positive result in that audio output now works properly.

Now when I access the 'Sound' settings, I now see a 'Line-out Built-in Audio' option under 'Output Device'. Prior to this the only option was a 'Dummy Output'.

I can now successfully test the audio output from within the 'Sound' settings application (and I hear the female voice appropriately on both the right and left channel), and audio output works properly when playing back a YouTube video via Firefox.

In summation, I was able to repeat the positive result using your updated kernel on a fresh install of Ubuntu 20.04.1 and audio output on this system works as expected.

Despite this, I wanted to make you aware of the error I received during the installation on the off chance that would be of interest.

I would like to thank you again for all of your help throughout the process, it is very much appreciated.

Please let me know if I can provide any additional information regarding this issue and I will be happy to do so.
